Inhalation:Corrosive! Inhalation of vapors can cause
coughing, choking, inflammation of the nose, throat, and upper respiratory
tract, and in severe cases, pulmonary edema, circulatory failure, and death.
Ingestion:Corrosive! Swallowing hydrochloric acid can cause
immediate pain and burns of the mouth, throat, esophagus and gastrointestinal
tract. May cause nausea, vomiting, and diarrhea. Swallowing may be fatal.
Skin Contact:Corrosive! Can cause redness, pain, and severe
skin burns. Concentrated solutions cause deep ulcers and discolor skin.
Eye Contact:Corrosive! Vapors are irritating and may cause
damage to the eyes. Contact may cause severe burns and permanent eye damage.
Chronic Exposure:Long-term exposure to concentrated vapors may
cause erosion of teeth. Long term exposures seldom occur due to the corrosive
properties of the acid. Aggravation of Pre-existing Conditions:Persons with pre-existing skin disorders or eye disease may be more
susceptible to the effects of this substance.

4. First Aid Measures

Inhalation:Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention immediately. Ingestion:DO NOT INDUCE VOMITING! Give
large quantities of water or milk if available. Never give anything by mouth
to an unconscious person. Get medical attention immediately. Skin
Contact:In case of contact, immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention immediately. Eye Contact:Immediately flush eyes with
plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.

5. Fire Fighting Measures

Fire:Extreme heat or contact with metals can release
flammable hydrogen gas. Explosion:Not considered to be an
explosion hazard. Fire Extinguishing Media:If involved in a
fire, use water spray. Neutralize with soda ash or slaked lime. Special
Information:In the event of a fire, wear full protective clothing and
NIOSH-approved self-contained breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure mode. Structural
firefighter's protective clothing is ineffective for fires involving
hydrochloric acid. Stay away from ends of tanks. Cool tanks with water spray
until well after fire is out.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Isolate hazard area. Keep
unnecessary and unprotected personnel from entering. Contain and recover
liquid when possible. Neutralize with alkaline material (soda ash, lime), then
absorb with an inert material (e. g., vermiculite, dry sand, earth), and place
in a chemical waste container. Do not use combustible materials, such as saw
dust. Do not flush to sewer! US Regulations (CERCLA) require reporting spills
and releases to soil, water and air in excess of reportable quantities. The
toll free number for the US Coast Guard National Response Center is (800)
424-8802.

7. Handling and Storage

Store in a cool, dry, ventilated storage area with acid resistant
floors and good drainage. Protect from physical damage. Keep out of direct
sunlight and away from heat, water, and incompatible materials. Do not wash
out container and use it for other purposes. When diluting, the acid should
always be added slowly to water and in small amounts. Never use hot water and
never add water to the acid. Water added to acid can cause uncontrolled
boiling and splashing. When opening metal containers, use non-sparking tools
because of the possibility of hydrogen gas being present. Containers of this
material may be hazardous when empty since they retain product residues
(vapors, liquid); observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection

Ventilation System:A system of local and/or
general exhaust is recommended to keep employee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it
can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH
document, Industrial Ventilation, A Manual of Recommended Practices,
most recent edition, for details. Personal Respirators (NIOSH
Approved):If the exposure limit is exceeded, a full facepiece
respirator with an acid gas cartridge may be worn up to 50 times the exposure
limit or the maximum use concentration specified by the appropriate regulatory
agency or respirator supplier, whichever is lowest. For emergencies or
instances where the exposure levels are not known, use a full-facepiece
positive-pressure, air-supplied respirator. WARNING: Air purifying respirators
do not protect workers in oxygen-deficient atmospheres. Skin
Protection:Rubber or neoprene gloves and additional protection
including impervious boots, apron, or coveralls, as needed in areas of unusual
exposure to prevent skin contact. Eye Protection:Use chemical
safety goggles and/or a full face shield where splashing is possible. Maintain
eye wash fountain and quick-drench facilities in work area.

12. Ecological Information

Environmental Fate:When released into the soil, this
material is not expected to biodegrade. When released into the soil, this
material may leach into groundwater. Environmental Toxicity:This material is expected to be toxic to aquatic life.

13. Disposal Considerations

Whatever cannot be saved for recovery or recycling should be
handled as hazardous waste and sent to a RCRA approved waste facility.
Processing, use or contamination of this product may change the waste
management options. State and local disposal regulations may differ from
federal disposal regulations. Dispose of container and unused contents in
accordance with federal, state and local requirements.
